Block raises 2026 outlook on strong quarter, says AI touches nearly all code

Fintech firm Block raised its full-year 2026 outlook after a strong Q2 performance. Gross profit surged 25% year-over-year to $3.17 billion, exceeding guidance. Adjusted operating income hit $855 million, and adjusted EPS of $1.02 beat estimates. Consequently, Block increased its full-year gross profit forecast to $12.51 billion and adjusted operating income to $3.47 billion. CFO Amrita Ahuja attributed the guidance hike to strong execution and momentum. Separately, the company revealed that agentic AI assisted in writing and reviewing nearly all production code changes in June. This follows a February AI-led restructuring that eliminated 4,000 jobs. According to Block, code changes per engineer have increased 150% since the start of the year.

Michael Saylor: Bitcoin Halved, My Digital Credit is Making Money

Michael Saylor discusses Bitcoin, digital credit, and corporate treasury strategies in a recent roundtable. He explains that while Bitcoin remains "digital capital" with no counterparty risk, its ~40% annual volatility makes it unsuitable for most institutional and retail capital. To attract this capital, he advocates for Bitcoin-backed "digital credit" and "digital currency" products. These offer low volatility against fiat currencies, generate yield, and compete with traditional money market funds, stablecoins, and other yield-bearing crypto assets. Saylor clarifies that these products are not meant to replace direct Bitcoin ownership but to onboard capital that otherwise wouldn't enter the Bitcoin ecosystem. He provides examples: during a period when Bitcoin fell 50%, his company's digital credit products (STRC, SATA) delivered positive returns of 3-4%, demonstrating their ability to strip out ~90% of Bitcoin's volatility. He frames "digital currency" as a fiat-referenced, yield-bearing, stable-value asset backed by Bitcoin, designed to meet the needs of the global capital pool. This approach, he argues, can expand the Bitcoin network's reach by 10x to 100x more effectively than pure education. The discussion also covers corporate finance for Bitcoin treasury companies. Saylor argues that equity issuance is not inherently dilutive if done above net asset value per share and if the acquired asset (Bitcoin or cash) supports future value creation. He distinguishes between debt with maturity dates and hybrid capital like preferred shares (e.g., STRC), which offer issuer options and do not force liquidation. Evaluating these companies requires modeling based on future Bitcoin price and volatility assumptions, not relying on a single metric like mNAV (market-adjusted net asset value). The business models are still evolving, and investors must analyze full disclosures to form a complete view.

Getting Ahead of the Tide and Drowning First: The Fall of 'Crypto x AI' Pioneer ai16z

"ai16z, an early pioneer of the 'crypto x AI' narrative, has officially shut down. In late 2024, its token launch sparked a massive speculative frenzy around AI Agent tokens, briefly propelling the project to a $2.6 billion valuation. However, by 2026, as functional AI agents from companies like Anthropic and OpenAI became mainstream reality, the crypto-native AI projects built largely on hype began to collapse. The founder of its underlying project, Eliza OS, announced the termination in a bitter post, citing legal threats from token holders and a depleted foundation. He expressed disillusionment with the crypto community, contrasting it with the 'optimistic' builders in pure AI. While the Eliza framework itself remains active as open-source software—ironically with contributions from AI like Claude—the token-dependent venture failed. The story highlights a core flaw: the crypto market often prices narratives far ahead of functional technology. When the promised AI future arrived, it was delivered by traditional tech companies with sustainable business models, not token projects. The episode suggests the initial path of 'tokenizing AI concepts' is broken. However, integration may still occur in reverse—with AI tools enhancing crypto analytics and trading—or in coordinating real resources like decentralized compute, as seen in projects like Bittensor and Render."

Changxin Rejects Apple's Price Pressure, Prices Not Lower Than Samsung and SK Hynix, Apple Loses Pricing Power

Apple recently attempted to negotiate lower-priced DRAM procurement deals with China's CXMT (ChangXin Memory Technologies) compared to its agreements with Samsung and SK Hynix but was rejected. CXMT stated its prices would not be lower, and could even be higher, than those of the South Korean suppliers. This refusal is attributed to CXMT's production capacity being largely secured by long-term contracts with major domestic clients like Huawei, Xiaomi, OPPO, Vivo, and Chinese internet giants. Consequently, CXMT feels no pressure to meet Apple's stringent terms. The backdrop is a significant surge in memory prices driven by the AI boom. As Samsung and SK Hynix shift more production capacity towards high-margin High Bandwidth Memory (HBM) for AI servers, the supply of conventional DRAM has tightened, causing prices to skyrocket. This has drastically increased the bill-of-materials cost for devices like iPhones, pressuring Apple's profits. Apple's traditional strategy of leveraging multiple suppliers for price competition has weakened, as memory makers prioritize more profitable AI-related orders. CXMT's confidence stems from achieving technological parity. Its DDR5 and LPDDR5X products have reached mass-production yields above 90%, closely matching Samsung's performance. With technical gaps closed, CXMT no longer competes solely on low prices. Furthermore, Chinese companies are wary of the risks associated with over-reliance on Apple's supply chain, citing cases like OFILM and Wingtech, which suffered severe losses after being removed from or impacted by US sanctions. This event signals a shift in the semiconductor industry's power dynamics. The AI-driven demand has transformed the market from buyer-centric to supplier-centric, where control over scarce, advanced production capacity grants pricing power. For Chinese semiconductor firms, the episode marks a transition from being low-cost alternatives to becoming equal suppliers with their own pricing authority, backed by domestic demand and technological advancement. Apple's loss of leverage with a mainland supplier underscores this changing era.

Tiger Research: Four Ordinary People's Stories Reveal the Ultimate Destination of Blockchain in 2036

Tiger Research: 2036 - Four Stories of Blockchain's Integration This speculative narrative presents four vignettes set in 2036, illustrating the subtle yet profound ways blockchain technology could reshape everyday life and global systems. Story 1: The Irrelevance of National Currency. In the inflation-plagued fictional nation of Zutopia, Judy, a longtime currency exchange worker, witnesses the endgame. Dollar-pegged stablecoins (USDT, USDC), once a niche tool, have completely supplanted the volatile local Bucks for daily transactions, salaries, taxes, and even government bonds, eroding traditional monetary sovereignty. Story 2: The 24/7 Global Casino. Lia, a young investor in Singapore, operates in a world where every asset—stocks, real estate, bonds—is tokenized and trades endlessly on borderless platforms. For her generation, constant, leveraged, global trading is the norm, contrasting sharply with the cautious, scheduled investments of her parents. Story 3: The Great Consolidation. Do-hyun, an infrastructure engineer, recalls the 2020s boom of countless independent blockchains (like the fictional "Allchain") that collapsed after incentive programs ended. By 2036, the landscape has consolidated into a handful of major, efficient networks, as users and liquidity coalesced around durability over fragmentation. Story 4: The End of the Banner Ad. Media entrepreneur Jae-hoon observes the final shift from human-centric advertising. With most web traffic now from AI agents, the old pageview-and-banner model is dead. A new machine-to-machine economy thrives via protocols like x402, where media companies charge AI agents micropayments for data access, creating a more reliable revenue stream than traditional ads ever did. Together, these stories depict a 2036 where blockchain is not a standalone revolution but an integrated, almost invisible infrastructure enabling global digital currency, seamless asset markets, consolidated networks, and a new paradigm for digital content commerce.
